In 2010, the U.S. Congress passed the historic health care reform bill that will provide some type of coverage for the millions of Americans without health care insurance. Just how widespread is the lack of medical coverage in 2016, years after health care reform was passed? The media claim that the segments of the population most at risk are women, children, the elderly, and the poor. The tables give the number of uninsured (in thousands) by sex, by age, and by household income in 2016.6 Using the appropriate summary statistics, graphical displays, statistical tests, and confidence intervals, investigate the accuracy of the media?s statement using these data. Be sure to discuss your assumptions, methods, results, and conclusions. (Note: Some totals between tables may not match exactly due to rounding.)
